STEAM-VALVE.

QPECIFICATION forming part of Letters Patent No. 337,537, dated March 9, 1886.

Application filed September 28, 1885. Serial No.178,381. (No model.)

To all whom it may concern:.

Be it known that I, ARIE VOGEL, of Lake, in the county of Cook and State of Illinois,

have invented a new and Improved Oscillating Steam-Valve, of which the following is a full, clear, and exact description.

My invention relates to the construction of steam-valves; and it consists of certain novel constructions and combinations, to be hereinafter described, and specifically pointed out in the claims.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a vertical sectional view of a portion of a steam-engine with my invention applied thereto, the valve being also shown in vertical section. Fig. 2 is a plan view of the valve-seat, the stem and valve being removed. Fig. 3 is a sectional view of thevalve, representing the position of the parts when the piston is advancing on the forward stroke. Fig. 4 is a sectional plan View taken on line 3 y, Fig. 3; and Fig. 5 is a vertical sectional View taken on line so :0, Fig. 4.

Referring now to the general construction illustrated in Fig. 1, A represents the cylinder; B, the piston; O, piston-rod, and D the eccentric-rod, which connects with a lever, E, that operates the valve-stern T.

The valve-seat F may be, as represented in Fig. 1, a portion of the cylinder-wall, or it may be an independent casting arranged,as shown in the other figures, to be fitted to the cylinder. This valve-seat is formed with two ports, a a, which each act alternately as the induction and eduction ports of the cylinder. The valveseat is also formed with an exhaust-port, b, and with a circular groove, 0, in which there is arranged a packing-ring, d, that fits in a corresponding groove, 6, formed in the lower face of the oscillating valve H, which said lower face fits fiat against the adjacent face of the valve-seat.

The valve H is formed with a central upwardly-projecting wall, f, thus leaving an an nular space between the outer wall, f, and the central wall, f, while the inner face of the wall f is hollowed out to form an annular recess, g. The annular space between the walls ff is divided into compartments 2', t", and i by partitions h h and h h; or the partitions h h might be merged into one solid block that would fill the spacej. The side walls of the partitions named are parallel with radial lines leading to the circular center of the valve. The partitions h h are diametrically opposite each other, and on either side of each partition there is a port. These ports are shown atkkandll, klc being induction and lleduction ports, the eduction-ports being formed in the compartment 2' in which there is also formed an exhaust-port, m, which is an elon gated oval opening in the center of the compartment, just over the exhaust-port b in the valveseat, said port b communicating directly with the exhaust-pipe a. The cover I of the valve H is made integral therewith.

A hollow valve-pivot, N, formed with two beveled bearing-surfaces, n a, arranged to fit closely against corresponding beveled seats b b, is provided with a screw-threaded end, 10, which engages with a female thread formed in the socket of the valve-seat F, an annular space, 9, being formed about thepivot between the two beveled surfaces, said space 9 being in register with the spacey of the valve H when the parts areput together, as shown in Fig. 1. The annular chamber formed by the space 9 g is arranged to be connected with the compartments 2' t" by apertures 0 0, formed in the wall f.

The valve-stem T is pivotally connected with a lug, 1", which projects outward from the valve H. When theparts have been properly adjusted by turning the pivot N to produce a proper pressure upon the overhanging portions, the pivot is locked in place by turning the set-screw s, so as to bring it to bear against the plug it, which will be advanced against the threaded end of the pivot, thus preventing it from turning.

For the purpose of properly adjusting the valve, I form the pivot N with a hexagonal part, 10, so that it may be engaged by an ordinary form of wrench.

Steam is supplied to the cylinder through the central passage of the pivot N, which communicates with the annular chamber formed by the spaces 9 9' through the ports 1) a, passing thence through the apertures 0 o to the chambers i i, and through the ports is or I k to the ports a or a of the valve-seat, and thence into the cylinder.

In operation the valve works as follows: When the piston is advancing, the valve will be turned so that the port it" will be in line with the port a, so as to deliver steam to the rear of the piston, the exhaust-steam at this tlme passing through the ports a and Z into the compartment 6, and thence through the ports at and b to the exhaust-pipe a. As thepiston advances, the valve will be moved by means of its connection with the eccentric, so that ust as the piston reaches its full stroke the induction-port is will be brought over the port a and the eduction-port Z over the port a, so that steam will be fed in in front of the piston, and the exhaust -steam will be discharged through the ports a and Z, the chamber or compartment i ports at and b, and pipe 12, the oscillating motion of the valve being repeated at each stroke, so that steam will be alternately fed in before and behind the piston, which will receive the full force of the steam in each direction of its stroke.

In order that the valve may be protected, I cover it with a shield or casing, M, formed with a slot, 12, through which lug 1* projects, the slot being elongated to allow for the reciproeating motion of the log, and the casing being secured and held in position by setscrews or tap-bolts c" c, which are threaded to engage with threaded sockets formed in the valve-seat.

Having thus fully described my invention,

I claim as new and desire to secure by Letters 3 5 Patent- 1. The combination, with the valve-seat and valve H, of a hollow pivot, N, and a packinga ring, (I, substantially as described.

2. The combination,with the valve-seat and valve H, formed with the beveled bearingsurfaces 1) 11*, of ahollow pivot, N, formed with corresponding]y-beveled surfaces n a and a threaded end, 19, substantially as described.

3. The combination, with the valveseat and 5 its groove 0, of the valve H, with its groove 0 a paeking-ring, cl, pivot N, formed with beveled surfaces a a", and pivot 1;,substantially as described.

4. The combination, with the valveseat 50 formed with ports a, a, and b, of the valve H, formed with ports Z Z, is k, and 'm, and hollow pivot N, formed with ports 12 12, substantially as described.

5. The valve H, formed with the chambers i, i, and i, ports 7c is, Z l, and m, and recess g, substantially as described.

6. The combination,with an engine-cylinder having ports, as a, a, and b, and the rotary reciprocating valve H, of the hollow pivot N, 60 having the ports 2) o, and the recess 9, substantially as described.
